PEOIFIGATION forming part of Letters Patent No. 772,196, dated October11, 1904.

Application filed January 30, 1903.

To all whom it may concern:

Be it known that I, FREDERICK S. WARD, of New Haven, in the county ofNew Haven and State of Connecticut, have invented a new and usefulImprovement in Eyeglasses; and I do hereby declare the following, whentaken in connection with the accompanying drawings and the letters ofreference markedthereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this specification,and represent, in

Figure 1, a front view of a pair of spectacles constructed in accordancewith my invention, connection at one end between the lens and the templebeing shown in section; Fig. 2, a top view of the same.

This invention relates. to an improvement in bifocal eyeglasses; and bythe term eyeglasses I mean to be understood as includingglasses whichare provided with temples and commonly known as spectacles or those witha nose-guard and .commonly called eyeglasses.

In the ordinary use of bifocal glasses the segments for .near work arearranged in the lower edge of the lenses, necessitating in many casesthat the wearer raise the head in order to look through thedistance-glasses The object of this invention is to so mount the lensesthat they may be revolved in the frames, so that the segments may beworn at the top of the lenses or at the bottom, as may be desired; andthe invention consists in-the construction as hereinafter described, andparticularly recited in the claim.

The lenses A B are the usual lenses and arranged in connection withsegments 0 D in For spectacles, as shown in Figs. 1 and 2 of the.drawings, the lenses are connected by double reversely bowed bridges E,and these lenses are connected with {the temples F by ball-and-socketjoints G. As

- having suflicient shown in Fig. 1 of the drawings, the lenses SerialNo. 141.110. (No model.)

are arranged with the segments at the top and so that the wearerconveniently looks through the distance-lenses; but the lenses may bereadily turned in their bearings, so that the segments will stand at the.bottom of the lenses, as indicated in broken lines. in which positionthey are in use for near work, the swivel-j oint between the lenses andtemples friction to retainthe lenses in either position. I

While I have shown a balland-socket connection between the lens and theframe; it will be understood that any swivel connection may be employedwhichwill frictionally hold the lenses in the desired position andpermit them to be revolved, so as to turn the segments from the top tothe bottom of the lenses. 1 v

I am aware 'that bifocal lenseshave been mounted in frames adapted to beturned so as to reverse the position of the segment, and do not,therefore, wish to be understood as claiming, broadly, such as myinvention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The herein-described bifocal glasses the the connection with the templebeing in line with the central horizontal axis of the lenses" Witnesses:
